Applications
Ferritic stainless steel ASTM A743 Grade CC50 is used for pump casings, impellers, valve bodies and seats in chemical manufacturing, mining and pulp-and-paper equipment. Other documented castings include bushings, cylinder liners and digester parts. Other cast components used in this material family include stationary pump casings, valve components and sleeves.
Typical industrial settings include chemical processing, mining and pulp-and-paper equipment. Aggressive liquids, sliding contact and suspended solids require assessment for the particular service.
